Four OCT-A devices go head-to-head. Was there a winner?
Mark Hillen |
Articles that directly compare the wares of competitors are common in consumer markets but pretty rare in the healthcare space. And yet, rather than pitting Hi-Fi components, mobile phones or cars against each other, a recent article in PLOS ONE (1) compared OCT-angiography (OCT-A) modules from Heidelberg Engineering (Spectralis OCT2), Optovue (RTVue-XR), Topcon (DRI-OCT Triton) and Zeiss (Cirrus 5000-HD-OCT).
There are a couple of caveats that should be noted up front. Heidelberg Engineering’s OCT2 module was still a prototype and the area it scanned was different to the other instruments (3 mm x 3 mm vs. 4.3 mm x 1.5 mm); the Optovue instrument was an older model that lacked eye tracking; and only 19 healthy subjects (with no history or presence of eye disease, cardiovascular disease or diabetes and a VA of 20/20 or better) were employed in the study, meaning that no diseased retinae were examined.
